11 Destinations in Asia Where Tourists Need Visas or ETAs

Asia attracts travelers with its variety, value, and depth, but entry rules are not as uniform as many Americans expect. Some destinations allow visa-free entry, while others require approval well before a flight is booked. Assuming the rules are the same across the region can lead to costly mistakes.

Visa and ETA requirements in Asia vary widely by country and passport. Some approvals are quick and electronic. Others involve applications, documentation, and waiting periods that affect when and how a trip can be planned. These details often get overlooked when travelers focus on routes, hotels, and itineraries.

For couples planning a trip, this is a practical issue that shapes everything from timing to flexibility. Knowing where advance permission is required helps avoid last-minute stress, denied boarding, or plans that fall apart before departure. It also makes it easier to compare destinations realistically, especially when juggling work schedules or limited travel windows.

We have identified 11 destinations in Asia where tourists need visas or ETAs. This list focuses on places where advance planning is essential and where understanding entry requirements early helps trips start smoothly and stay on track.

China

China requires most U.S. travelers to obtain a visa in advance, and entry rules are applied strictly. Visa type must match the purpose and itinerary, with specific documentation tied to accommodations and onward travel. Transit exemptions exist but are narrowly defined and often misunderstood. Border officers verify paperwork closely, and discrepancies can result in denial.

Takeaway: China travel works best when visas are secured early and itineraries remain consistent with the approved application.

India

India requires U.S. travelers to apply for an e-Visa before arrival. Applications must match travel dates, entry airports, and purpose precisely. Errors are not corrected on arrival, and approval must be received before boarding. Processing times vary, which can complicate last-minute trips.

Takeaway: India entry depends on careful e-Visa preparation and confirmation well before departure.

Vietnam

Vietnam requires advance authorization for most tourists, commonly through an e-Visa. The visa is linked to specific dates and entry points, and flexibility is limited once issued. Airlines verify approval before boarding, and arrival without proper authorization is not permitted.

Takeaway: Vietnam trips are smoother when travelers apply early and confirm entry details match the approved visa exactly.

Laos

Laos requires a visa for U.S. travelers, available either online or on arrival at select entry points. Requirements can vary by border crossing, and payment methods are not always consistent. Processing can take time, especially during peak travel periods.

Takeaway: Laos entry is easier when travelers confirm visa options for their specific border and carry required documents and payment.

Cambodia

Cambodia requires most tourists to obtain a visa, commonly through an e-Visa or on arrival. Approval is checked before entry, and incomplete applications can delay arrival. Rules are enforced consistently, particularly at major airports.

Takeaway: Cambodia travel works best when visas are secured online in advance to reduce wait times and entry issues.

Sri Lanka

Sri Lanka requires U.S. travelers to secure authorization before arrival, most commonly through an ETA system. Applications are completed online and linked to passport details. Approval is checked before boarding, and travelers arriving without authorization are not admitted. Processing times can vary, particularly during busy travel periods, which makes last-minute plans risky.

Takeaway: Sri Lanka travel is smoother when authorization is completed well ahead of departure and verified before booking flights.

Myanmar

Myanmar requires U.S. travelers to obtain a visa in advance, typically through an e-Visa system. Entry is limited to approved airports and land crossings, and visa validity dates are enforced strictly. Travelers who arrive outside approved entry points or with mismatched dates may be denied entry.

Takeaway: Myanmar trips require careful alignment between visa approval, entry location, and travel dates.

Indonesia

Indonesia requires U.S. travelers to obtain a visa or authorization, commonly through a visa-on-arrival system that still requires advance preparation. Passport validity, onward travel proof, and fee payment are checked closely. Travelers who assume visa-free entry applies universally may face delays.

Takeaway: Indonesia entry works best when travelers confirm visa type, passport validity, and payment requirements before departure.

South Korea

South Korea requires Americans to register through an electronic travel authorization system before arrival. Approval must be granted prior to boarding, and airlines verify authorization at check-in. The system links passport details and travel intent, and errors can prevent boarding.

Takeaway: South Korea travel is easiest when authorization is completed early and details are double-checked before finalizing plans.

Nepal

Nepal requires a tourist visa for U.S. travelers, commonly issued on arrival at major airports. Fees vary by length of stay, and payment must be made in accepted currencies or formats. Processing can be slow during peak trekking seasons.

Takeaway: Nepal entry is smoother when travelers arrive with required photos, payment, and a clear length of stay.

Pakistan

Pakistan requires U.S. travelers to obtain a visa before arrival, usually through an online application system. Approval must be secured in advance, and documentation requirements can be detailed. Border officers verify paperwork carefully on arrival.

Takeaway: Pakistan travel requires early visa application and close attention to supporting documents.
